MEANS FOR PROPELLING VESSELS.

Specification of Letters Patent.

Patented Oct. 1O, 19( 5.

Application filed September 23, 1904:. Serial No. 225,627.

This invention relates to that class of devices employed for driving boats, ships, and water craft of all kinds wherein paddles or buckets secured at intervals to endless bands, belts, or chains are carried through the water by the travel of the belts, which are driven by suitable mechanism.

The invention is an improvement on the propelling mechanism illustrated in the United States Patent No. 652,770, granted to me July 3, 1900, and the features thereof will be hereinafter fully described and their novel characteristics carefully defined in the claims.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a plan view of a vessel provided with the propelling means; and Fig. 2 a side elevation of the same, partly in section. These are general illustrative views showing the propelling means applied to a boat of the same character as that illustrated in my former patent. Fig. 3 is an elevation, on a larger scale, of the propelling means or mechanism with the casing removed at the line a in Fig. 4; and Fig. at is a transverse section substantially at :r" in Fig. 3. Fig. 5 is a fragmentary sectional view, the plane of the section being taken at :11" in Fig. 8. Figs. 6, 7, and 8 are enlarged detail views of the bucket-carriage.

Respecting the vessel V (seen in Figs. 1 and 2) it will only be necessary to say thatit is or may be constructed in the manner fully described in my former patent, No. 652,770, and that the propelling means will in this case be located at the central part of the boat, the buckets dipping into the water in the channel extending longitudinally of the boat. In Figs. 1 and 2, P designates the propelling means as a whole, and C the channel in the boat.

Referring now more particularly to Figs. 3, at, and 5, 1 designates a frame, in which are rotatively mounted two shafts 2 2, provided at their ends exterior to the frame with cranks 3. Parallel rods 4 connect the cranks at the respective sides in the manner of locomotive parallel rods, whereby both shafts 2 will be driven at the same rate of speed when 1 power is applied to one.

One of said shafts is driven by power of any kind, and this may be through the medium of a wheel 5 thereon, which gears with a driving wheel or chain. (Not shown.) On each shaft 2 are mounted two sets of radial driving-arms 6, of which there may be four in each set. As herein shown, the four arms radiate from a boss 7, keyed 0n the shaft. On the outer face of each set of arms 6 is secured a circular rim 8, which is concentric with the shaft. 1n the frame 1. and in the same vertical planes with the rims 8 are fixed beams 9, the positions of which are clearly seen in Fig. 1, and between the rims 8, carried on the two shafts 2, are fixed frames,(designated b 'FinFig. 3.) The upper and lower beams 10 of these frames are parallel with the beams 9 and form with the latter two parallel channels 11, as clearly seen in Fig. 3. Fig. 5 shows the preferred method of constructing these inner frames.

The endless bands 12, which carry the buckets 13, are formed by preference each of two plies of thin steel of suitable width, and said band is made in sections which are connected by bucket-carriages 1%, the construction of which is shown in Figs. 6, 7, and 8. Each carriage consists of two like plates 15, placed face to face and embracingbetween them two outer rollers 16, and two similar inner rollers 16. It maybe stated here that for simplicity and convenience in removing the rollers each roller rotates on a headed pin 16, which extends through the plates 15, and the pin has in it a hole through which extends a spring pin or key 17. ln the plates 15 is a square hole 18 to receive the ends of the square bar 19, on which the bucket 13 is secured. At the respective ends of the plates are secured jaw-pieces 20, in which the band-sections are secured by set-screws 21. The jaw-pieces are coupled by pins 22 of the same character as the pins 16. These bucket-carriages 1 1 move along the channels 11, the outer rollers bearingon the beam 9 cxteriorly and the inner rollers bearing on the beam 10 interiorly, except at the ends of the main frame 1, Where the bands pass about the rims 8 in the manner of a belt on a pulley-rim. As these rims rotate with the arms 6, which engage the bars 19 and move the bands, there will be no play of the band over the rim except when the shift is made in backing.

Obviously the specific details of construction of the parts as herein shown need not be closely adhered to, as they may be varied without departing materially from the present invention.

The construction of the propelling means may be employed also in vessels constructed differently from the Vessel V herein shown.

2. A device for the purpose specified, having a frame provided with channels 11, above and below, an endless bucket-carrying band made up of sections, bucket-carriers in said band between the respective sections, each having two outer rollers and two inner rollers to roll on the outer and inner walls of 1 said channels, and buckets secured to bars having square ends engaging square holes in the opposite carriages.

3. A device for the purpose specified, having a frame provided with parallel channels 11, two above and two below, two shafts 2 mounted rotatively in said frame, two bosses 7 on each shaft, a set of four driving-arms on each of said bosses, a circular rim 8 on each set of arms, said rims being in the same vertical plane with the upper and lower channels at that side of the frame, endless bands 12 extending through the respective channels and bands and adapted to travel along said chanover the said rims, roller-carriages l t in said nels, buckets provided with bars 19 mounted at their ends in said carriages, and parallel bars connecting cranks on the said shafts 2, substantially as set forth.

In witness whereof I have hereunto signed my name, this 15th day of September, 1904:, in the presence of two subscribing witnesses.

KARL P. HANGL.
